A filled trench is disclosed. The filled trench comprises: a pair of conduits (3a, 3b) for delivering fluid with a different temperature in each of the conduits, the pair of conduits being surrounded by filling material; a first section (5a) filled with a filling material of a first type (4a), wherein the first filled section (5a) of the filled trench occupies a space surrounding a first conduit (3a) of the pair of conduits; and a second section (5b) filled with a filling material of a second type (4b), wherein the second filled section (5b) of the filled trench occupies a space surrounding a second conduit (3b) of the pair of conduits. The filling material of the first type (4a) has a first thermal conduction coefficient and the filling material of the second type (4b) has a second thermal conduction coefficient, the second thermal conduction coefficient being different from the first thermal conduction coefficient.
